Application March 22, 1929, Serial No. tttfltii Mi Claims.

This invention relates to controlling devices for tabulating machines, and particularly to devices for controlling the entering of debit, credit and net amounts or a plurality of such amounts at. a single operation of the machine.

One of the principal objects of the invention is to provide a preliminary representation device wherein different parts may be moved to represent a debit and a credit thereby causing the entire device to represent the net amount.

Another object is to provide simplified means for sensing debits and credits from the punched record cards, whereby the capacity of the card may be greatly enlarged.

With these and other objects in view as will be apparent as the specification proceeds, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, particularly pointed out in the appended claims and illustrated in the accompanying draw ings, in which:

Fig. 1 is a vertical sectional view showing the means for reading the data from the record card.

Fig. 2 is a vertical sectional view showing the numerical preliminary representation devices.

Fig. 3 is a view showing the side elevation of all of the contact plates of a section and indicating graphically how they combine and what they indicate. a

Fig. 4 is a skeletonized front elevation of certain frames and shafts.

Fig. 5 is a fragment of a record card showing the numerical code punching.

Fig. 6 is a diagrammatic representation of a representative circuit.

Fig. 7 is a view similar to Fig. 2 but showing the alphabetical control devices.

Fig. 8 is a view similar to Fig. 1 but for the alphabetical control.

Fig. 9 is similar to Fig. 3 but for alphabetical control.

Fig. 10 is similar to Fig. 5 but for alphabetical and numerical code punching.

Fig. 11 is an end view of the commutator.

Fig. 11 is an enlarged detail section of one denominational set of contact plates showing also one of the cooperative contactor bars, the proportions being exaggerated for the sake of clearness.

Fig. 12 is an enlarged fragmentary detail perspective view of the same.

Like characters of reference refer to like parts in all views.

Referring to the drawings, in detail, and in particular to Figs. 1 and 2, 20 represents the tabulator-pin-guide plate of the well known construction, familiar in the commercial field as the Powers tabulator; and El 1 represents the tabulator pins guided by said plate. In the machine 5 as at present constituted and commercially known, there are twelve pins 2! in each column of which the nine pins toward the front of the machine control the setting of respective stops to enter the nine significant digits in the tabulator head. 10 This is done by intermediate connections between the pins 2| and the known tabulator stops 22 which are mounted in the stop-basket 23.

However, in the present invention the pins 2| of each row, are divided into two sections, each section controlling, as desired, one or more rows of stops 22. By this is meant that an item punched in either the upper or lower half of the card may be entered in any desired zone of the tabulator or simultaneously in a plurality of zones, this being made possible by an intermediate connection box or device such as shown in my pending application Serial Number 324,427, and also indicated in Fig. 6 hereof. In order to do this, the record must be specially punched with combinational punchings. That is, each perforation no longer represents a single digit as in prior devices, but combined punchings represent the different digits according to a predetermined scheme and the upper and lower halves of the cards represent difierent data, although all the data on the card may be read at a single cycle of operation.

While the herein described means shows means for effecting control for alphabetical and symbol control, it may be well for the present to consider the devices only in their digit control and later in this description describe the extension to alphabetical and symbol control.

As shown in Fig. 5, the zones of punching have been reallocated so that the positions formerly used for I2, II, 0 and I, may now, by combinanational punchings, represent I to 9, and the positions formerly used for the digits 4 to I, inclusive, may now, by combinational punchings; represent I to 9. Thus the data capacity of the card is doubled. The code punchings for numerals as shown are as follows: a punch in the position formerly allotted to I2 now represents 9; combination of perforations at positions I2 and I I now represents 8"; combination of perforations at positions I I and 0 now represents 1"; combination of perforations at positions 0 and I now represents 6; combination of perforations at I2" and I now represents 5, a single perforation at position I I now represents 4"; combination of perforations at I 2 and 0 now represents 3"; combination of perforations at I I and I now represents 2; a single perforation in the former 0 position now represents l and a single perforation in the I position represents 0. In like manner the lower half of the card is coded as follows:

It will be recalled from the known Powers tabulator as commercially on the market, that wherever a perforation occurs in the data card, a pin 2| will be raised during the cycle of operation in which the card is passed through the machine. But in the known structure only one series or line of data is read from each data card, whereas in the present invention it is necessary to provide means for sensing two series and conducting the sensed amount from each series to a diiferent portion of the tabulator head. Such means is provided and will now be set forth.

Sensing means It may be well at this point to make reference to my prior application Serial Number 324,427 of which the present device is in some respects a modification and extension.

On the edge of the pin plate 20 there have been placed the numerals 0 to "l2, inclusive, indicating the values of the pins 2| in the Powers machine as at present on the market. Directly over the pins 2! in the l2, ll, 0, I, 4, 5, 8, and 1 positions are respective contactor bars which are indicated respectively as 200, 20!, 202, 203, 200A, 20IA, 202A and 203A, the first four bars being raisable by the pins co-operative with one half of the record card and the second four by the pins co-operative with the other half of the record card. Inasmuch as each of these eight bars rests with its lower end immediately over a respective pin 2|, it is obvious that each bar has an upper and a lower position in one or the other of which the bar will stand according to whether its pin 21 is raised or lowered. It will be remembered that a perforation in a record card permits raising of the respective pin 2| and consequently in the present construction will result in the raising of the respective contactor bar. It will be understood, of course, that there is one series of eight contactor bars for each column of analyzing pins 2!, the several series being duplicates of each other.

Each of the contactor bars 200, 20L 202, and 203 is provided with a respective upper laterally extending contactor or brush 20$ and a respective lower laterally extending contactor or brush 205; and similarly the bars 200A, ZMA, 202A, and 203A have upper and lower contactors 204A and 205A, the contactors 204 and 205 being arranged in different horizontal planes from 204A and 205A. The several brushes 204, 205, 204A and 20523. are insulated from their supporting bars.

Universal bars 25, 25, 26 and 21 are supported.

and guided in slots 28in the framework 29. Rods 24,25,26, and 27 are either made of insulating material or are suitably insulated from parts with which they cooperate. Secured to rods 24, 25, 26 and 21 and movable therewith are a plurality of vertically disposed carriers or tie and spacing members 30 and 3| preferably made of insulating material, members 30 extending above the rod 24 for a purpose to be presently set forth. Mounted on the rods 24, 25, 26 and 21 are two series of contact carriers, one series above the other. Each series of contact carriers consists of five thin contact plates insulated from each other in any desired manner and all secured together and held between spacers 30 and 3| on' rods 24, 25, 26 and 21. The five plates of each upper series are indicated respectively by reference numerals 208, 209, 2l0, 2H and 2|2 while those of the lower series are indicated at 208A, 209A, 2IOA, 2| IA and 2l2A, the plates 208 and 2| 2 of the upper series and 208A and 2l2A of the lower series being the outer plates of these series.

And now the purpose of these series of plates will be considered, bearing in mind that those having an A as part of the reference characters are co-operative with those contactor bars having an "A as part of the reference characters. Current isconducted to the contact carrier 2l2 or 2l2A at one side of each series of plates by any desired means such as spring brushes 2| 3 and 2|3A, and brushes 2| 4 and 2| 4A contacting the carriers 208 and 208A at the other side of the series are provided with connections (later fully described) leading to desired add and subtract electro-magnets 32 and 33. is completed through the five plates of any selies, the correlated magnet or magnets 32 and/or 33 are operated to stop the correlated preliminary representation slide so as to control entering the digit represented by the position of the series of contact carriers at the time of completing such circuit. The means by which the carrier plates are connected at the proper instant includes contacts on the carrier plates and the brushes 204 and 205 and/or 204A and 205A. This means of connection will now be described.

As shown in Fig. 3 the plates 2082I2 and 208A-2 l 2A are formed with upper contact fingers 2| 5 and lower contact fingers 2H5; and the five plates of a series are held between plates 2|! of insulating material of suiiicient breadth to permit exposure of the ends only of the fingers M5 and M6 to the action of the brushes 204, 205, 204A, and 205A. Normally, the brushes 204, 205, 204A and 205A are all down, so that the brushes 204 and 204A would be in position to contact the several contacts 2 I 5 as they are moved across the brushes. But if any of the bars 200 to 203 and 200A to 203A is raised, then its brush 204 or 204A is raised out of efiective relation to the contacts 2|5, and its brush 205 and 205A is raised into effective relation to the contacts 2 I 6.

It may be well at this point to consider Fig. 3 somewhat more in detail. It will be noted that the contact bars have been divided into zones by vertical lines, the zones being indicated by the letters a to m and a: to z. The width of a zone is the distance between the centers of the bars 200 to 203 or 200A to 203A. The contacts 2I5 and 2l6 within these various zones have been primed with the letter of that zone. These contacts have been so arranged that for each of the above described code punchings of the card there will be only one position at which the circuit will be closed through the five contact bars and that position will be such Thus when a circuit that the operation of the correlated magnet 32 or 33 will stop the respective slide according to such code punching. The bars 208-2l2 have been shown here as identical with bars 208A-2l2A which is correct as far as the relation of the contacts is concerned but of course, the bars themselves are made with the entire series of contacts arranged to co-act with the respective brushes as clearly shown in Figs. 1 and 5.

lid The several slide bars 200--2[l3, 2tDA-2ll3A are supported in upright position and guided in slots in plates 3 and 35 and normally rest upon the upper tabulator pinplate 26.

Considering now the means for causing contact 15 plates 268-292 and 208A-2l2A to traverse the brushes 2lil-2@ii and 20lA2D5A, 31? represents a rotating drive shaft of the tabulator. Upon the end of this shaft 317 is pinned a disk 32 carrying a laterally extending pin 39 which rides in a slot it] 20 formed in a rocker ll pivoted at 442 and connected .by a link 13 to one end of an arm M, the other end of which is fast on a rock-shaft d5. This rock shaft 65 carries a pair of depending arms id to which are pivoted links ll formed with slots ltl 25 thru which the rod 25 extends. Springs 69 anchored at one end to the links t? and at the other to the rod 25 tend to constantly hold such rod in the left-hand ends of slots 28 as viewed in Fig. 1.

It will now be apparent that rotation of shaft 3t 30 will cause rotation of disk 38 which will cause pin it to eiiect rocking of rocker M, whereby link it will be caused to rock arm M, shaft 55 and depending arms it. This causes reciprocation of links ll and rod 25. Rods 2 25, 26, and 27 to- 35 gether with the tie and spacing members 3i] and 39 and the several series of contact plates form a unit so that reciprocation of rod 25 efiects reciprocation of all of the contact plates so as to traverse the several brushes 2M3, 2M, 253A, 2l lA.

40 Turning next to the circuits closed by the completing of the connection from one outside plate i to the other of any series of contact plates 2@8- M2 and 28A2l2A, a suitable source of electric energy is indicated at at from which current is 45 passed over a lead iii to a brush 52 which contacts a rotary commutator body 53 mounted on shaft Bil for rotation thereby and having a contact strip 545. A second brush 55 also contacts the periphery of commutator 53 and is connected 50 by lead and branches to the several spring brushes 23, MESA. Brushes 2E3, 292A, 2116 and 2 l lies are supported on through rods 57, and while the rods til of brushes 2l3, ZltlA need not be of insulating material, the rods Sill of brushes 2M,

55 2l li l must be of insulating material or suitably insulated from the brushes mounted thereon.

brush 2%, 2MA is connected by a respective lead 58 to a respective cross rod 59 of the connection box and each cross rod may be to connected by means of sliding connectors iii and $2 to any one or plurality of vertical strips 63 and elements 6i and 53 controlling addition, and. t2 and 6d controlling subtraction. The connection box lid is fully described in my pending 65 application Ser. No. 324,427 filed .December 'l, 1928, to which reference may be had for a more complete description. Each of the vertical strips 153 connected to one side of a respective adding magnet by a lead 65; and similarly, each of 70 the strips t l is connected. to one side of a re spective subtracting magnet 33 by a lead 65. lhe other sides of all of the magnets 32 and 32 are grounded to a lead tl'back to the source till.

' "in order to hold the several magnets 32 and i5 energized after the same have been energized and during such portion of cycle as is necessary, even though the energizing contacts 2 l5 and 2 I6 may have passed out of energizing position, I provide what I term holding" circuits for these magnets. A third brush 66 contacts the com- -5 mutator disk 53, and a portion of the contact strip lid is notched at 59 so that this brush will not contact strip 55 until shortly after brushes 53 and 55, for a purpose hereinafter set forth in connection with alphabetical control. For presout purposes it is enough to say that all three brushes are efiective whenever a digit control is efiected by contacts 205 and me. This brush 68 is connected by a lead it and branches to the armature ll of each and every magnet 32 and 33.

The positive or inlet side of each magnet 32 and 221s connected to a respective contact l2 positioned to be engaged by the armature ll of the respective magnet when in closed position. Hence when once the armature of a magnet 32 or 33 is closed it will be held closed by the circuit from 5t thru Si, 52, 5d, 6d, lit, H, i2, 32 or 32, and til, until this circuit is broken by the rotation of commutator disk 53 sumciently to bring contact strip 55 out of engagement withvbrushes 52 and (it. During this time the mechanism of the tabulator head has completed its recording of the required amounts.

Considering a concrete example, presume that it is desired to enter a credit of 29 and a debit of i5 and to automatically determine and enter the net amount of it; and that the credit is entered on the top half of the card (usually devoted to 112 to 3) and the debit on the lower half of the card (usually devoted to :l to "d). The card for this example therefore has a tens column punched with perforations in the l l" and l positions to indicate the tens credit entry 2, and with a single perforation in the t position to indicate the tens debit entry i. The units column is punched in the 62 position to indicate the units credit entry 9 and in the d and l positions to indicate the units debit entry 5. When this card is fed into the machine, it will cause the raising of the bars'2lll, 2%, 282A associated with the tens denominational contact carriers 28 to 2l2 and 288A to 2(12A of one zone; and the bars 2%, will and teas associated "with the units denominational contact carriers of the same zone. (It will be remembered that the columns of a punch card are divided into vertical zones according to the requirements of the business) An inspection of Fig. 3 will readily show that when the tens bars 2lld2l2 have moved far enough for the contacts 211th of plates 20 l and 202 to have come in line with bar 203, contacts 2M2 of plates 2% and 2M! will be in line with bar 22, contacts 206 of plates 2% and 2m will be in line with bar 2M, and contacts 20570 of plates 2 it so and 2M will be in line with bar 26m. Nowit will be recalled that bars 2% and 2il-i have been raised and that bars 2% and 2% have remained down, so that the brushes 2% of bars 2M and 2% and brushes 26 of bars 2% and 2&2 bridge Proceeding with our example, the tens bars 208A-2I2A during their excursion eventually bring the contacts 2I5i of bars 208A and 209A into contact with the brush 204 of bar 203A and at this time contacts 2I69' of bars 209A and 2IOA meet brush 205 of bar 202A (which has been raised due to a perforation in the 6 position), contacts 2I5k of bars 2IOA and 2I IA meet brush 204 of bar 20IA and contacts 2I5l of bars 2IIA and 2I2A meet brush 204 of bar 200A. The circuit is thus completed and the correlated magnet 33 is operated to effect stopping of the respective subtraction slide in its I position.

In like manner the units bars 208 to 2I2 and 208A to 2I2A are bridged when they arrive at the.

Locking mechanism When bars 200203 and 200A-203A have been raised, means are provided for locking raised bars in raised position and lowered bars in lowered position. For this purpose, each of these bars is provided with an upper notch I3 and a lower notch 14. The upwardly extending portions of members 30 hereinbefore mentioned, normally contact a cross rod I5 and hold it to the right in Fig. 1 against the tension of springs I6. This rod I5 together with another rod I1 and a plurality of cross strips I8 form a locking frame. This locking frame is supported and guided by projecting the ends of rods I5 and TI through short slots in the framework. Each cross strip I8 is provided with lateral pins I9 for engagementwith the notches I3 or I4 of the bars 200203 and 200A--203A. Preferably'there is only one bar I8 for each two rows of bars 200203 and 200A-203A, the pins I9 projecting on both sides of bars I8 so as to co-act with the adjacent bars 200--203 and 200A203A on each side of each bar I8. As soon as the spacers 30 start their excursion toward the left in Fig. 1, the locking frame is permitted to follow up until its pins 19 engage the notches I3 of all lowered bars and the notches 14 of all raised bars. Upon the return of spacers 30 the locking frame is forced back to ineffective position, and the raised bars 200-203 or 200A --203A drop back to lowered position. Thus springs 16 offer no resistance to bars 200-203 and 200A-203A while being raised and lowered, but hold them in proper position during the required portion of the cycle.

Setting up the net Having considered in the foregoing pages how the debit and credit punchings in a card control the energizing of adding magnets 32 and subtracting magnets 33, the means controlled by .such magnets for producing the net balance will now be discussed.

Referring particularly to Fig. 2, there is provided a plurality of adding or credit magnets 32 having armatures H and stops similar to the magnets 52, armatures I04 and stops I05 of my said prior application. There is also provided a plurality of subtracting or debit magnets 33 having armatures II and stops 8|, each of the latter having a guide pin 82 riding in a slot 83 in a respective guide bar 84. Each stop rod 8I has a laterally extending portion 85 at its upper end.. Each magnet 32 is connected in circuit through the connection box 60 with such bars 2082I2, 208A2I2A as are allotted to the desired denominations of the desired credit entry, so that bridging of the respective bars causes simultaneous operation of the respective magnet 32; and in like manner each magnet 33 is conous operation of the respective magnets 33, by

means above described.

While it has been considered in the respective example under consideration that the debit and credit items are in the same zone on the card, it is to be understood that they may be in different zones and that credits may be on either the upper or lower half of the card or both and similarly with: debits. Of course, the debits and credits which are to be related must be caused to control correlated circuits by a connection box as shown in my said application and indicated herein at 60 or by directly creating such circuits in any desired manner such as that used in the Hollerith type of tabulator or in any other suitable manner.

The several bars 84 are mounted on two crossrods 86 and 81 and spaced apart in any suitable manner, there being one bar 84 for each row of stops 22. The bars 84 are positioned directly beneath the respective rows of stops 22. Slidably mounted on each bar 84 is a slider formed with two side plates 88, spaced apart at the bottom by a bar 89 to which the plates 88 are riveted. The bar 89 is formed with stop teeth 90 to cooperate with the associated stop rod 80; and is formed with a spring anchor 9| to which one end of a spring 92 is secured. The other end of spring 92 is anchored to any suitable stationary part such as a rod 93, and tends constantly to draw the plates 88 toward the right as seen in Fig. 2. I

The plates 88 rise on each side of the respective bars 84, and the plates are formed with ears 94 or other suitable means, passing across and riding upon the respective bars 84. The plates 88 extend upwardly so that each pair of plates forms a guideway for a respective subtraction slide 95. Each subtraction slide 95. is formed with a downwardly extending portion 96 which rides on the-respective bar 84, and also is provided with a pin 91 which extends into a bayonetslot 98 in plates 88 and formed so as to provide a stop shoulder 99. The upper part of slot 98 is ten spaces long and the lower part is eleven spaces long. The upper edge of each subtraction slide is formed with a plurality of stop teeth or shoulders I00, the zero stop being considerably higher than the others. Each subtraction slide 95 is also formed with an abutment shoulder I0 I, and an upwardly extending shoulder I02.

Springs I04 hold up the right-hand ends (as seen in Fig. 2) of slides 95 and tend constantly to hold the shoulders IOI against a universal rod I05 and to hold pins 91 in line with shoulders 99. Rod I05 forms part of a frame having side bars I06 and a cross-tie rod I01 which frame is reciprocated at each cycle of the machine by links I08 pivotally connected to I05 and at I09 to upper arms IIO secured to and rocked by shaft 45. It will thus be seen that universal bar I05 not only controls movement of slider 95, but, through pins 91, also controlsmovement of the slides 88 which are moved back to normal and retained there by pins 91. The frame I05-I06I0I is supported and guided by extending bar I05 into slots in the framework and by forming the members I06 L- shaped and extending studs Ill through parallel with I 01 and in the same horizontal plane as I85, so they may ride in the same slots somewhat extended.

Above the slides95 are respective guide bars or rails 1 52 which are mounted at one end on the stationary rod M3 and at the other on the mov= able rod ll l. Mounted on one side of each bar M2 is a summation slide 1! l 5 which is held to and guided on the bar M2 by bent over tabs or cars MB. This slide M5 is also formed with an upwardly extending stop-setting finger Ml, an elevated portion H8, an inclined cam face M8, a shoulder H28 and a restricted portion i211. Each slide H5 also carries a hook lZZ pivoted to its lower edge and held up by the correlated portion 85 of a stop 86, and in the plane of the correlated subtraction slide 85 and adapted to be dropped into engagement with the teeth Mill thereof. Also the lower edge of each slide H5 is formed with a finger H23 which is bent into the plane of the shoulder E02 of its own denomina-= tional slider 95, and a finger i2 3 bent into the plane of the higher order subtraction slider 85. A universal carrying bar 25 extends above all of the rails M2.

Mounted on each rail E E2 is a secondary slider M6, the same being arranged along the side of the rail H2 opposite to slider M5 and having bent over ears l2? and i128, the latter extending into the cutaway portion 132! of the slider M5 on the same rail M2. The restricted portion lit is of such extent that from the shoulder 828 to the ear i it is slightly more than ten spaces of movement, that is, the distance is equal to ten times the distance between centers of the stops 22 plus the width of ear H28. Thus it will be seen that slider M5 after it has moved ten spaces will pick up the secondary slider H28 and carry it with it. The secondary slider 528 is also pro== vided with a stop-raising finger I128 slar to the finger ill of the slider M5.

Negative carrying Whenever slider H5 is moved more than ten spaces it is necessary to deduct one from the next higher slider and this is accomplished as follows:

Presuming that 2 has been added this will mean that slider 88 has moved to bring the eighth tooth on (the second tooth from the left) into co-operative relation with stop 88 before the stop 88 will have stopped it, the slider also moving the same distance and then moving until its pin ill strikes the shoulder 99. if 8 isto be subtracted in this column, the magnet 33 of that column will lower the hook E322 into engagement with the eighth tooth of slider (the second tooth from the right). Slider till will thus be carried sixteen spaces thereby moving its finger ill out of the field of stops 22, but it will have picked up the secondary slider andmoved it six spaces so that it will stand under the (3 pin. When slider lib moves from its tenth step to its eleventh step its incline its has engaged the universal bar i125 thereby depressing the right hand end of slider lit) and its finger 9243 will have pressed down the right hand end oi the next higher slider 85 so that the pin or the latter comes below the stop 98 or its member 8? and this next higher slider 95 will, therefore move one additional step so that the cooperating finger ill or 128 will be moved to the next ad jacent stop 22 thereby deducting one from this next higher slider.

In order to rock the frame comprising uni versal bar i ill and members M2 so as to chest raising of all of the desired stops 22, the outer member H2 is provided with a roller 530 which is engaged and raised by a cam portion or lug I3! on member I88 as it nears the end of its excursion to the right in Fig. 1.

Pursuing our problem 2915=14, it will be seen that the tens slide 88 moved far enough before being stopped to have brought element H1 under the 2" pin 22 if no subtraction were being done. But as l was to be subtracted, hook H22 became efiective on the 1" shoulder I00 and when slider 95 completes its excursion, it will have moved the slider 5 to bring its element Ml under the l pin 22 of the correlated row.

In like manner, in the units column, slider 88 will have stopped at the 9 tooth (first to the right), and hook l22 will have engaged the 5" shoulder lllb so that when this slider 95 completes its movement the cooperative slide H5 will have its element H1 under the 4 pin 22 of that row. It will be easier to understand this action if it is remembered that slider Hills moved only by slider 95 and only after hook 822 becomes efiective, while slider 88 is merely a limiting means for determining the excursion of slider 95.

Now consider the converse proposition 15-29=-ll4. The units hook I22 becomes effective on the 9" shoulder I88 and moves the slide lit in unison with the slide 88 until the element M5 is under the 5" stop 22, at which time slide 88 is stopped and slide 95 continues to move slide Mb ten spaces further thereby bringing element 028 under pin 5 (the complement of the digit i of the result) and efiecting a negative carry. In the tens column the slides 88 and 85 move idly until hook i122 is brought down into engagement with the 2 shoulder I88 after which all three slides move one space in unison bringing element Ml] under the 8 pin, when slide 88 is stopped. Slide 85 now moves eleven spaces by virtue of the carry from the units column thereby bringing finger I28 under the "8 pin (the complement of the digit i of the result) and efiects a carry, and as each higher slide H5 will, therefore, move eleven spaces, 9 will be set up.in each of the higher orders so that the negative amount it will be positively entered complementally, thereby effecting correct result.

Alphabetical control It is at times necessary to devote a portion of the tabulator to the printing of'alphabetical or belie tter, and in the Powers tabulator as at present constituted, an alphabetical sector is used comprising two parts, one of which is brought into action by a perforation in the card controlling the zero stop 22. In the present instance, to perforation. in the "3 position or in the 9 position controls means for operating the zero pin 22 so as to release the second portion of the alphabetical sector. The means whereby this is accomplished is as follows:

The alphabetical arrangement of types used in the standard Powers alphabetical tabulators has been accepted, the same being set forth in United States Patent smas er. However, the code punching has been changed so as to punch two lines of matter on a single card although this matter may be" transcribed as a single line by the tabulator. A desirable alphabetical code punching is shown in Fig. 10. lit is also necessary in increasing the capacity thus to utilize six contact carrying bars and six brush carriers. The

specific mechanism for alphabetical work is best 7 shown in Figs. 7, 8, 9 and 10 and is constructed as follows:

For each column of the card devoted to alphabetical or symbol control, there are provided two series of six contact carriers each indicated as 300, 30I, 302, 303, 304, 305, and 300A, 30IA, 302A, 303A, 304A, 305A, respectively. As in mere numeral control, the two series are similar being merely spaced so as to bring their contacts 2I5 and 2I6 into cooperative relation with their respective brush carriers. The alphabetical brush carriers are indicated at 306, 301, 308, 309, 3I0, 3H and 306A 301A, 308A, 309A, 3IOA, 3IIA and carry brushes 204, 205, 204A and 205A, carri'ers 3H and 3| IA being provided only with brushes 205A as their only function is to bridge directly across from plate 300 to 3| l or from 300A to 3 I IA whenever a punch occurs in the 3 or the "9 position. The elements 300-305, 300A305A, 3063II and 306A3IIA are constructed and operate the same as similar parts of the numeral mechanism hereinbefore described. Consequently, associated elements which are duplicates of those used in the numerical mechanism are given the same reference characters in the drawings.

The bars 300305 or 300A-305A are connected by means of the connection box 60 to respective magnets 230 provided with armatures 23I each of which is connected by a link 232 with a bellcrank 233 pivoted on a rod 234. The lower arm of this bell-crank is provided with a slot 235 in which rides a pin 236 of a vertically movable bar 231 provided at its upper end with a turned over finger 238 and intermediate its ends with a stop pin 239. The mechanism is so timed that when one of the magnets 230 is operated by the bridging of the contacts 2I6X (i. e. where there is a perforation in the 3 or 9 position) the brush 68 will be in the notched out portion 69 of the commutator and consequently this magnet will be operated and then let go as its holding-circuit wi 1 not have been closed by contact of brush 68 with the contact strip 54. The vertically movable bar connected with this particular magnet will, therefore, be raised and then lowered by a spring 2310, which will set mechanism for operating the zero stop 22 for releasing the alphabetical sector, which mechanism will now be set forth.

In that unit of the mechanism devoted to alphabetical work each of the sliders 880 mounted on the rails 84 is formed in a single piece having ears 240 slidably securing the respective slider 880 to the respective rail 84 and formed with teeth 90 and with an upwardly extending finger 24I carrying a pin 242 extending through a slot 243 in the depending finger 244 of a slider; 245 mounted on a respective rail H2. The slider 245 is formed with ears 246 embracing and movably securing the slide 245 to the rail H2, and carries a stop-lifting finger 241. Also mounted on each rail H2 is a second slider 248 provided with ears 249 which embrace the rail H2 in such manner that the slider 248 is movable along the rail and cross-wise of the rail so as to render its stopraising finger 250 effective for raising the zero stop 22 of the tabulator. The slider 248 is provided with an upwardly projecting hook element 25I which is adapted to engage and hook into a retaining ledge 252 formed on a member 253 carried by the guide plate 254 of the pins 22. The slider 248 is also provided with an upwardly extending finger 255 to which one end of a diagonal- -ly disposed spring 256 is attached, the other of the spring being attached to the member 253 as shown in Fig. 8. The spring 256, therefore, tends constantly to pull the slider 248 toward the right in Fig. 8 and also to keep the free end 01' the slider down in contact with its rail I I2. The connected fingers MI and 244, of sliders 880 and 245 contact bar I05, and slider 245 engages the upstanding spring finger 255 to hold the slider 243 normally to the left.

When, however, a punch occurs in a position other than 3 or 9" position. the required magnet 230 is operated after brush 68 has left notch 69 and the holding-circuit holds the magnet energized, the pin 239 having engaged the proper tooth 90, and being held so as to maintain finger 241 under the proper stop 22. Of course where there are double punchings, both the stop 250 and stop .241 will be brought to operative positions and will raise respective stops 22 when the universal bar I I4 is raised. It may be well at this point to note that when the stop finger 250 is to be set for active work (i. e. when a hole is punched in 3 or 9 position), the bar 231 is operated at approximately the instant that rod I05 starts its rearward excursion. This rocks slide 240 slightly so as to bring hook 25I into position to hook on ledge 252. As bar I05 is moving rearwardly, spring 256 draws hook 25I onto ledge 252. It will be remembered that the holding circuit is not efiective at this time, and consequently member 23! drops back to lowered condition before any tooth 90 arrives at pin 233. The operation progresses and at some point in the travel of slides 880 and 245, depending on the secondary aperture or apertures of the combinational punchings, the member 231 is again operated. stopping these slides with finger 241 under the desired pin 22. After the several fingers 241 and 250 are set, bar H4 is raised as in Fig. 1 and in any column where both fingers 241 and 250 are active the 0 pin and one of the other pins will be raised with consequent control of the tabulator head as is well-known in the art. Thus means are provided for both numerical and alphabetical work.
